Twenty-six ectopic pregnancies located strictly within the isthmus were treated surgically using conservative laparoscopic techniques. In each and every case, the Triton monopolar electrode was used to perform salpingostomy which was followed by aspiration of the trophoblast. This therapeutic approach is very reliable since only one failure was observed (3.9%), requiring a further operation during which salpingectomy was carried out by laparoscopy. It was possible to evaluate subsequent fertility for 11 patients, seven of whom (63.6%) obtained an intrauterine pregnancy and only one patient (9.1%) had a recurrence. This highly satisfactory prognosis is perfectly comparable with that obtained with treatment via laparotomy with segmental resection of the isthmic portion of the tube and immediate or delayed anastomosis. These very encouraging results mean that conservative laparoscopic treatment presents an advantageous alternative to classic surgical treatment for isthmic ectopic pregnancies, in that the patients are spared a laparotomy.
